I am going to side with those who say it is not the game itself that needs to specifically cater to women in ordder to attract them to the game.
One reason for this is that I think that trying to define what 'all women' and 'all women gamers' want/find enjoyable in an RPG is about as useful as trying to define what 'all male gamers' and by extension 'all males' want/find enjoyable in an RPG.
Anecdotal evidence from my gaming group:
[sblock=A short history of how my gaming group began]
I really wanted to play D&D after years of having no fixed abode. Having settled down at last I rounded up friends for a 'boys night playing D&D'.
5 players and myself. Only 1 of the 5 had ever played D&D (OD&D with his bro who ran solo adventures for him where his characters were insta-killed in a variety of colourful ways by his account).
The initial idea was to rotate the gamenight from house to house and the wife at each house would be invited to sit in and run Hogart, the dwarven cleric. No... not sexist. Hogart the dwarven cleric was the character I would have wanted to play if I wasn't DM.
First night: Only 3 showed. 2 bailed by phone 5 minutes before game start time. I was gutted. My wife stepped in and took a character on (she had played with me before but never 4th edition which was brand new and shiney at the time) and I ran Hogart. The campaign began.
A player short, my wife came the next night as well, and our hosts wife ran Hogart.
My sister-in-law found out my wife was playing. Suddenly it wasn't a boy's night! She was furious! Why wasn't she invited? She joined the campaign the next weekend where our following host's wife also sat in as hogart. The idea of Boy's Night was abandoned in the dust where it belonged and the group grew to 6.
To cut a long story short, every wife who played wanted to continue to play on a more permanent basis. The group's size swelled to 'far too many' and soon rotations between spouses began while the other stayed at home looking after the kids or arrangements were made for the kids to sleep over at the house we were playing so both could attend.
Nearly everyone involved were RPG virgins. All had heard about D&D and were curious but had no idea how it actually worked. All knew about the notorious 'suicide/murder' incidents. All admitted being put off a bit by the stigma of 'those kind of people play those wierd games'. One woman was adamant she wouldn't be into it. She was hooked within 10 minutes and became the most fervant of my players in organising the next session.
Several of the husbands lost interest in time due to the lateness of the times we were forced to play and the length of the sessions ( a big group doesn't help that). Their wives happily took their seat on a permanent basis at the table.
We played nearly religiously every weekend. game time was 10.30 pm (after kids were put to bed, which is later in Spain) to 2.30-3am in the morning. They reached lvl 11 as the campaign drew to a close when me and my wife moved back to NZ a few months ago. [/sblock]
Cast:
Judith, my wife: Elven ranger: Loves RP, being saucy, and kicking ass in battle but from a distance where she doesn't get beat up on. No interest whatsoever in charcter creation.
Lele, my sister-in-law: Drow sorceress: Loves RP, being intimidating, coming to the game fully dressed up as her character, tactical combat, character creation. She is the person most likely to DM apart from me.
Mar (female): Hogart, dwarven cleric: Prefers exploration, puzzles, skill challenges out of combat. Got a bit bored feeling she always had to heal by the end. She wanted to pack mre of a punch in combat.
Elsa (female): Shifter two weapon ranger: prefers combat, loves getting up into the middle of things and going savage. Very direct and not so tactical. Would often instigate things with flashes of absolute RP brilliance both in and out of combat, and other times sit back and let others move the action. Very creative approach to problem solving.
Javi (male): Goliath paladin: Prefered combat. Not so tactical. An instigator when the group got bogged down with too much ovethinking a problem. Did not enjoy RP as much.
Each one of my players was totally different both in approach and playstyle. Which is my point. There were 2 other women that played in the campaign at different times and 3 other men. Their play styles/approach were equally as diverse.
Everyone that played agreed that it was a really cool, enjoyable game, including the 2 that 'lost interest'.
So, in my opinion, based on my experience, its not the game itself thats an issue, and i extend that beyond the issue of including 'more female gamers' amongst the ranks, to an issue of swelling the ranks of gamers worldwide in general. Its a stigma that surrounds the game with a negative aura of 'its something that wierd dudes like that play'.
I encountered that attitude when I returned to NZ a few months ago with my brother-in-law ( a hard core rocker (guitarist, drummer, singer ... hehehe and flautist. Jethro Tull style of course)) when I suggested we play. "That's a nerds game bro. i'm not playing a nerds game." It makes me laugh to think back to last weekends game (our third game now) where he was getting really annoyed becasue he had to keep interrupting his turn to deal with the kids. "Why does something always happen when its my turn!!" Ahahaha ... in short, he loves it!
Its the stigma we need to attack somehow. We need to change the attitude towards the game and those that play it. The game itself is awesome in ALL ... let me say that again, it bears repeating ... ALL its forms. And as many have already said, we the gamers can have a lot of influence in that respect.
